I have a routine that evaluates a polynomial equation that have 3 variables
x,y,z of orders 1,2,3 the coefficients of the polynomial are in an array.
This routine is quite slow and I'd like to optimize it.
Any suggestions?
simply put pts is a vector of

Hi there
Please help me to optimize this code for speed
I added /O2 to compiler settings
I added /Oe to compiler settings for accepting register type request , but
it seems that is not allowed and if I remove register type for "l" , time of
generating codes doesn't change
the original code makes some files , but I removed that section to make it
simple for you to read
please help me to optimize it for faster running

I'm writing a large Javascript application (uncompressed source around
400K) which is doing almost all the initialisation it needs to in a
just-in-time manner. However, I have included an option for almost all
of this to be done when the application first starts.
Under this circumstance, and since the last few nightly builds of
Mozilla, I've been getting:

Hi,
My son is writing a program to move a character. He is
using the numbers on the keypad to indicate the direction
of movement:
7 8 9
4 5 6
1 2 3
Each number has a direction except for '5'. So in
his switch statement, he omits a case for '5':

In particular, this question goes out to the Microsoft C++ development
team. Back in June, Ronald Laeremans posted the following message. Has
the optimizing compiler been included with the standard edition of VC++
yet? Don't think that we've forgotten about it....
Thank,

A little confusing with setting up optimizing options with 2003 .NET.
Under the Optimization Tab. if you set to /O1 or /O2 is the program ignoring
the settings for Inline Function expansion, Enabling of Intrinsic?
Would seem these should be greyed out to let you know.
Bigger question is what have people found in setting up the optimizing?
Using /O1 or /O2 ? Any ideas would be greatly appreciated.

Hello Group,
I have a table that has millions of records in it.
About 100 records are added every 5 minutes (one per OIDID) (the sample
provided below has data for 2 OIDIDs (99 and 100)
And I have a webpage that executes 9 queries one after the other, and then
displays the results on the webpage.
When the database was empty, this process was very quick.
But, as the DB grew, it became slower.

Without resorting to asm chunks I'm working on a few small routines
which manipulate bitmasks. I'm looking for any guidance on writing C
in a manner which tilts the compilers hand in, if possible, a
compiler/underlying processor independant way : althought to be fair I
cant see this stuff on anything other than x86, but who knows.
I found some ok info here:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
